1. Material Overview
The EN 10216-2 P265GH TC2 seamless pipe is a high-quality, non-alloy steel product designed for elevated temperature applications. It complies with the European standard EN 10216-2, which specifies technical delivery conditions for seamless steel tubes used in pressure equipment. The designation P265GH indicates its minimum yield strength (265 MPa) and suitability for high-temperature service ("GH" stands for "Gaseous Hydrogen" resistance).
2. Key Features
Superior Mechanical Properties:
High tensile strength (410-530 MPa) and yield strength (≥265 MPa), ensuring structural integrity under pressure.
Excellent creep resistance for long-term use at temperatures up to 450°C.
Chemical Composition:
Optimized alloy composition with controlled carbon (C: ≤0.20%), manganese (Mn: ≤1.40%), and silicon (Si: ≤0.40%) for weldability and durability.
Low sulfur and phosphorus content enhances resistance to brittle fracture.
Manufacturing Process:
Produced via hot-forming or cold-forming seamless processes, eliminating weld seams and enhancing uniformity.
Heat-treated (normalized or normalized rolled) to refine microstructure and improve mechanical performance.
3. Technical Compliance
EN 10216-2 Standard: Guarantees compliance with dimensional tolerances, pressure ratings, and testing protocols (e.g., hydrostatic testing, non-destructive testing).
PED 2014/68/EU Certification: Suitable for pressure equipment applications under the EU Pressure Equipment Directive.
TC2 (Technical Delivery Condition 2): Ensures specific impact energy requirements at low temperatures (-20°C), enhancing safety for critical environments.
4. Applications
Power Generation: Steam lines, boilers, and heat exchangers in thermal power plants.
Oil & Gas: Transport of hydrocarbons and process fluids in refineries.
Chemical Processing: High-temperature reactors and piping systems.
Industrial Infrastructure: Pressure vessels and pipelines requiring reliability under cyclic loading.
5. Quality Assurance
NDT (Non-Destructive Testing): Ultrasonic testing (UT) or eddy current testing (ET) ensures defect-free production.
Traceability: Full material certification (EN 10204 3.1/3.2) with batch-specific chemical and mechanical test records.
6. Advantages
High Temperature Performance: Maintains strength and oxidation resistance in demanding thermal environments.
Seamless Construction: Eliminates weak points, reducing leakage risks and enhancing longevity.
Versatility: Compatible with welding, bending, and machining processes for customized installations.
